An undulating tangle of interlocking sine waves that contain four to seven pointed stars which further contain flower-like radial abstract designs, is part of what you have here. You also have curved edge diamonds inside other curved edge diamonds, and twisting vines.
The result is a complicated eye candy of dark blue, black, white, and baby blue. Lots of internal dots and stripes. You can look at this design many times before you know everything that is in here.
